Dominique Dujardin VP IT Shared Services Europe chez XPO Logistics Europe at XPO Logistics Europe
5.0★
Software Development Review from Dominique Dujardin
The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly.Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.

Their affordable rates are a cherry on the cake. It's difficult to find these kinds of perfect combinations.

Will McDonald VP Product at Conductor

Web Development Review from Will McDonald
I was able to dictate requirements at a high level without having to deal with the details. The Admios team was able to make technical level decisions on their own. They were a first class partner of the team.
Mark Griffin Director of Engineering at Latent AI
4.8★
Software Development Review from Mark Griffin
Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)
Matt Attaway VP, Software Engineering at Off the Grid
4.7★
Mobile App Development Review from Matt Attaway
Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

Sketchy method of cold calling to get leads by claiming they talked to someone else at my org that they did not in fact talk to. Called on my personal cell phone. Would not do business with them if the engage this this type of misleading lead generation.

Arrange for an interview and ask about the development process and project approach.
Select a Flutter development company with proven experience in your industry and project, align with your team's values, and offer post-launch support.
Need help finding a US Flutter development company? Visit our Marketplace and tell us about your project. We’ll match you with top companies for free.
What red flags should I avoid when selecting a United States Flutter development company?
When selecting a United States Flutter development company, avoid the following red flags:
Limited or no Flutter projects in its case studies and portfolio
Lack of knowledge in Dart code, state management, RESTful APIs, JSON, and other Flutter frameworks and widgets
Skips the user research and quality assurance (QA) processes
Weak security and compliance practices
Unrealistic timelines
Doesn’t provide post-launch support and maintenance
Ambiguous project ownership
Multiple client reviews that highlight problematic traits, like poor communication and project delays
What factors affect the pricing of a United States Flutter development company’s services?
Key factors that affect the pricing of a US Flutter development company’s services include:
App complexity: The core features and functions, number of screens and devices, user roadmaps, and overall deployment architecture
UI/UX design: Elements like custom animations, illustrations, interactive elements, and the number of page templates
Tech stack: Costs associated with software licensing, testing platforms, third-party integrations, custom library, server space, and infrastructure
Development team: The level of expertise required, and the number of team members (e.g., developers, designers, DevOps, QA specialists) needed to handle the project
Project timeline: Shorter project turnarounds usually require larger teams or overtime work, increasing costs
Regulatory requirements: Industries like healthcare and finance require more stringent security features and extensive QA testing, which can lead to higher costs due to increased workload
On average, you can expect to pay $15,000-$40,000 for a simple Flutter app and $80,000-$150,000 for more complex solutions.
How long does a typical United States Flutter development project take?
Typically, a simple Flutter app with basic design components and limited integrations can take between 10 and 17 weeks. In contrast, a complex app that requires real-time data handling and elaborate UI/UX design can take around 30-47 weeks.
Here’s a timeline breakdown:
Research and strategy: 2-5 weeks
UI/UX design and prototyping: 2-8 weeks
Development: 4-20 weeks
QA testing: 2-8 weeks
Deployment and post-launch support: 1-6 weeks
Do Flutter development companies in the United States provide ongoing support?
Yes. Leading US Flutter development companies provide ongoing support and maintenance in addition to their initial service warranty. Typically, this comes in the form of an extended service level agreement (SLA) or a flexible engagement model, which allows long-term, more in-depth app maintenance after the initial launch.
Ongoing support services include performance monitoring, security patch installations, platform updates, feature enhancements, and third-party integration management.
